Npm Error while i try to execute npm run dev command in my terminal

Question

I am a fresher and started my career just 4 months back.

I am using Ubuntu and laravel for the development of my project.I am trying to compile a .js file for which i installed npm and bower in my project folder. Installation was smooth and is complete.

But while executing the "npm run dev" i am getting the below error.

I executed the below command :

sudo n latest And the error is :

npm run dev

> npm run development


> @ development /
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

events.js:167
      throw er; // Unhandled 'error' event
      ^

I used the below code in my root and the issue got fixed.

sudo npm install -g PACKAGE-NAME --unsafe-perm=false --allow-root

I used below to install all the packages.

sudo npm install -g --unsafe-perm=false --allow-root 

Npm is working fine now.

Thanks for all your help.

应该将 webpack-dev-server 降级为：

npm install --save-dev webpack-dev-server@2.9.7
